Long-Term Retention of Random Sequential Digital Information with the Aid of Phonemic Recoding: A Case Report

Abstract

A single S learned a random sequence of 1,152 digits in 34½ hr. with the aid of a prelearned phonemic recoding system, while he was able to learn only one-third of that length without phonemic recoding in the same period of time. After a 3-mo. retention interval, S remembered two-thirds of the learning sequence, while in the control condition there was no evidence of recall. Utility of multiple recoding of binary sequential information was demonstrated. Results were compared with previous findings on phonemic recoding. Practical applicability of phonemic recoding of sequential digital information was suggested.
